DEVELOPMENT AND JUSTIFICATION OF A SCARIFIER WITH A CONE DISC FOR BEAN SEEDS

Abstract

Currently, in the context of Western sanctions, the main goal of the agriculture of the Russian Federation is food security and reducing import dependence. The modernization of agricultural machinery, as well as the search for new ways of pre-sowing seed treatment, will increase the germination of seeds and provide agricultural livestock with high-quality fodder legumes. The paper considers an experimental scarifier of legume seeds, which makes it possible to scarify the seeds of legumes, thereby increasing their germination. The article describes the theoretical basis for the movement of seeds along a conical surface, considers the method of discrete elements, which underlies the Rocky DEM software package, which allows modeling complex systems of models. Laboratory studies were carried out, during which the angle of repose was determined for two varieties of alfalfa seeds (Sarga and Vega) and eastern goat’s rue seeds. On the basis of the obtained modeling data, an experimental scarifier with a scarifying working unit was constructed and production experiments were carried out, during which the quality of processing and germination of seeds of oriental goat’s rue on the experimental scarifier were determined.
